Wednesday’s menacing storm dumped more rain on New York City than Hurricane Sandy did — wreaking havoc on area roads and transit systems, experts said.

In Port Washington, LI, a mudslide buried two cars along Harbor Park Road. No one was hurt.

But the foul weather did claim the life of a Queens motorist who lost control of his vehicle during an early-morning drive on the Long Island Expressway, officials said.

The relentless rain caused flooding and closures on the West Side Highway and the FDR Drive. Stretches of highways in Westchester, including the Hutchinson River Parkway, the Bronx River Parkway and the Cross County Parkway, were closed, with conditions so bad that some cars stuck in water had to be towed out.
